The flat glass pH and platinum ORP sensors support water samples and suitable flat surfaces. For dry paper or fabric, moisten the test area with a few drops of distilled or deionized water as directed in the manual. Follow the stated preparation method; this does not establish suitability for every surface or chemical.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #B7D0BF;border-radius:8px;margin:0 0 10px;background:#fff;\"\u003e\u003csummary style=\"font-family:'Open Sans',sans-serif;font-weight:300;box-sizing:border-box;font-size:1rem;line-height:1.2;font-weight:600;padding:16px;cursor:pointer;\"\u003eHow should I calibrate pH before the first test?\u003c\/summary\u003e\u003cdiv style=\"font-family:'Open Sans',sans-serif;font-weight:300;box-sizing:border-box;padding:0 16px 4px;\"\u003e\u003cp style=\"font-family:'Open Sans',sans-serif;font-weight:300;box-sizing:border-box;font-size:1rem;line-height:1.75;margin:0 0 16px;\"\u003eThe manual recommends at least two pH calibration points before use. With the supplied USA buffers, start at pH 7.00, then use pH 4.00 and, when needed, pH 10.01. Complete the sequence without switching the tester off. The instrument supports one to three automatic points and can also use the NIST series through its settings.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #B7D0BF;border-radius:8px;margin:0 0 10px;background:#fff;\"\u003e\u003csummary style=\"font-family:'Open Sans',sans-serif;font-weight:300;box-sizing:border-box;font-size:1rem;line-height:1.2;font-weight:600;padding:16px;cursor:pointer;\"\u003eIs the ORP calibration target always 222 mV?\u003c\/summary\u003e\u003cdiv style=\"font-family:'Open Sans',sans-serif;font-weight:300;box-sizing:border-box;padding:0 16px 4px;\"\u003e\u003cp style=\"font-family:'Open Sans',sans-serif;font-weight:300;box-sizing:border-box;font-size:1rem;line-height:1.75;margin:0 0 16px;\"\u003eNo. The included standard is 222 mV at 25°C, but its reference value changes with temperature; for example, it is 227 mV at 20°C.

For better measurement conditions and probe life, the manual advises avoiding sample solutions below 5°C or above 45°C. Calibrate close to the sample temperature, with a difference of less than 10°C.
